Odorless and Overflow-less Toilet System

ABSTRACT

The technology described herein provides an odorless and overflow-less toilet system. The technology provides for the removal of odor at its source and aids in overflow protection. The technology provides a toilet system having a second chamber running in fluid communication with a first chamber and a second exit port to allow for the continuation of the second chamber flow to a trap assembly. The trap assembly is configured to separate exhaust odors and overflows. The trap assembly prevents sewage gasses from escaping back through the toilet. The trap assembly allows overflows to be routed back to a sewage out line. The trap assembly provides for the flow of odors from the toilet with an inline exhaust fan. The inline exhaust fan pulls odors from the toilet through the second chamber and exit port of the toilet through the trap assembly and then through the inline exhaust fan to exit.

FIELD OF INVENTION

The field of invention is an odorless and overflow-less toilet or urinalsystem. More particularly, a system to remove odor at its source and aidin overflow protection.

BACKGROUND OF INVENTION

It has been highly desirable to create a toilet or urinal system thatoffers both odor and overflow protection. While many inventions havebeen found that address odor removal, and other inventions that addressoverflow protection, no known prior art has been found that addressesboth odor removal and overflow protection. Prior art odor removal andprior art overflow protection devices are either expensive, verydifficult to repair or maintain, or both.

Earlier U.S. Pat. No. 5,809,581, while this system fulfills itsobjective of odor removal, it would cease to function in the event of anoverflow condition. The conduit from the toilet to the fan would becomeblocked by fluids that could not escape.

U.S. Pat. No. 7,302,714 shows ports and floats integrated in the toiletbowl that could be blocked by solids in the event of an overflow thuscreating a maintenance issue and allow sewage gasses to escape backthrough the toilet and into the atmosphere.

And U.S. Pat. No. 7,383,594 has a second drain port with screen thatcould also become blocked with solids and thus creating overflowingconditions and maintenance issues in the event of an overflow.

SUMMARY OF THE INVENTION

The invention provides a system for means of odor removal and overflowprotection at the source, the toilet bowl or urinal. The system iscomprised of three main components connected together with PVC or castiron conduits.

One item is the toilet bowl or urinal with a second chamber running influid communication with the originally designed first chamber and asecond exit port to allow for the continuation of the second chamberflow to the unique trap assembly to allow of exhausted odors andoverflows.

Another item is the unique trap assembly (U.T.A.) which allows for theseparation of exhausted odors and overflows. The U.T.A. is a speciallydesigned trap assembly that is engineered to allow the system tofunction properly for each type of toilet or urinal, whether floor orwall mounted. The U.T.A. prevents sewage gasses from escaping backthrough the toilet. The U.T.A. allows overflows to be routed back to thesewage out line. The U.T.A. allows for the flow of odors from the toiletor urinal by the use of an inline exhaust fan. The U.T.A. is maintainedby a trap primer made into the toilet or urinal to be described in moredetail later.

The third component is the use of an inline exhaust fan. The inlineexhaust fan pulls odors from the toilet or urinal through the secondchamber and exit port of toilet or urinal, through the U.T.A., thenthrough the inline exhaust fan where odors are exhausted to the outsideatmosphere.

The three components are connected with PVC or cast iron pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 3 is a cut away view of the floor mounted toilet 1 The tank 21shown or flushing valve, not shown, is the supply source of water 31when flushed. When flushed, water exits the tank 21 and enters the firstchamber 15, then flows through a plurality of holes 17 into the bowl ofthe toilet 1. The force of the incoming water washes the waste outthrough the first exit port 20. Odor and overflows exit through aplurality of holes not shown or a continuous vent 18, shown.

FIG. 4 is a schematic cut away of the unique trap assembly U.T.A. 2. Thefive connection ports are as such; sewage from the toilet 1 enters theU.T.A. 2 through port connection 25 and exits through port connection 4to sewage waste. Odor 5 and overflows 27 from toilet 1 enters theU.T.A's 2 port connection 24. Odor 5 is exhausted through the U.T.A.'s 2exit port connection 22 by way of inline exhaust fan 3. The trap 28within the U.T.A. prevents sewage gasses from escaping the U.T.A. 2.

FIG. 5 shows a schematic cut away view of system in normal operation.When toilet 1 is flushed, waste 29 exits through U.T.A. 2 and out towaste. When inline fan 3 is energized, odor 5 is removed from toilet 1and removed to outside atmosphere.

FIG. 6 shows a schematic cut away view of flushing operations. Whentoilet 1 is flushed, water 31 leaves the tank 21 travels through firstchamber 15, then exits through a plurality of holes 17, enters the bowl32 thus forcing the sewage 29 to exit through the U.T.A. 2 exit port 4.

FIG. 7 shows a schematic cut away view of odor 5 removal operations.When inline fan 3 is energized, the odor 5 exits the toilets 1 throughthe second chamber 16 and vents 18, then odor 5 travels out the secondtoilet 1 exit port 19, then through the U.T.A. 2, then through theinline fan 3 to the outside atmosphere.

FIG. 8 shows a schematic cut away view of overflow 27 operations. Whentoilet 1 becomes clogged 26 the overflow 27 flows through the secondchamber 16 and vents 18, then overflow 27 out the second toilet 1 exitport 19, then through the U.T.A. 2 and out to waste.
